GOLLAPSIBLE-BOX BLANK.

Application filed January 20, 1922. Serial No. 530,608.

5 New Jersey, and having a post-ofiice address at No. 115 Broadway, New York city, have invented certain new and useful Improvements in Collapsible-Box Blanks, of which the following is a full, clear, and exact specification.

In Letters Patent No. 1,4L13,108, dated April 18, 1922, I describe an improved collapsible tube package employing an enclosing box made diamond-shape in cross-section. My invention relates to an improved blank for making such a box, and my object is to produce a blank for the purpose which in its folded position may be passed through the usual pasting machine to permit the over-lapping edges to be gumined.

In order that the invention may be better understood attention is directed to the accompanying drawing forming a part of this specification, and in which:

Fig. 1 is a plan View of the blank illustrating a possible modification by dotted lines at the bottom;

Fig. 2, a plan view showing the blank in folded position for pasting;

Fig. 3, a perspective view of the complete box; and

Fig. 4, a perspective view of one end of the box, the locking flap being in open position.

In the above views, corresponding parts are represented by the same numerals. The blank comprises four panels 1, 2, 3 and 4, with scorings 5, 6, 7 and 8. The over-lap 9 for gumming is next to the outer panel; it is shown next to the panel 4. One of the outer panels, shown as the panel 4, is formed with diamond-shaped flaps 10 and 11 at its ends, said flaps, when the blank is fiat, facing outwardly. The next adjacent panel, in

' this case the panel 3, is formed at its ends with diamond-shaped flaps l2 and 18, facing oppositely to the flaps 10 and 11.

Two triangular flaps 14 and 15 are preferably used for purposes of strength, but they may be omitted. If used, these triangular flaps may be formed on the panel 2, in which case the diamond flaps 12 and 13 will be provided with two tongues 16 and 17 which look into the opening afforded by the panel 1. Or the flap 15 may be formed on the end of panel 1, as shown in dotted lines in Fig. 1, leaving the lower edge of panel 2 plain, in which case the tongue 17 will be formed on the diamond flap 11, as shown in dotted lines in Fig. 1, so that the .tongue 17 will look into the opening afforded by panel 2. When the blank is in folded position for gumming, as shown in Fig. 2, the diamond flaps lie within the sides of the folded blank, and therefore the blank can be passed through the gumming or pasting machine.

Having now described my invention, what I claim as new therein and desire to secure by Letters Patent, is:

1. A blank for collapsible boxes, diamondshape in cross-section, comprising four panels, one of the outer panels being formed at its ends with diamond-shape flaps facing outward, the adjacent panel being formed at its ends with diamond-shape flaps facing inward, an over-lap on one of the outer panels, and a tongue at the top and bottom of the blank formed on one of said diamondshape flaps, substantially as set forth.

2, A blank for collapsible boxes, diamondshape in cross-section, comprising four panels, one of the outer panels being formed at its ends with diamond-shape flaps facing outward, the adjacent panel being formed at its ends with diamond-shape flaps facing inward, an over-lap on one of the outer panels, a tongue at the top and bottom of the blank formed on one of said diamond-shape flaps, a triangular flap at the top of the blank on one of the other panels, and a triangular fiap at the bottom of the blank on one of the other panels, substantially as set forth.

This specification signed and witnessed this eighteenth day of January, 1922.
